Description

  The present invention relates to a container with a nozzle.

  As a container with a nozzle, there is a problem that the content remaining at the tip of the nozzle after discharging the content solidifies and prevents the next and subsequent discharges. If such a solidified material is generated in the nozzle, the tip It was necessary to scrape it out with a stick-like material. A nozzle in consideration of this point has been proposed. (For example, refer to Patent Document 1).

The nozzle is a nozzle in which a valve member is fitted and fixed to the tip of the dispensing cylinder, and the valve member is inward from the rear end of the inner surface of the peripheral wall with the outer peripheral edge fitted and fixed to the tip of the dispensing cylinder. A support base formed by extending a flange, extending a plurality of support legs in the circumferential direction forward from the inner peripheral edge of the flange, and providing a valve seat plate having a back surface peripheral edge connected to the front end surface of each support leg; The inner surface of the valve seat plate and the outer surface of each support leg is fluid-tightly fitted to close the opening between the support legs, and the outer surface is fitted to the inner surface of the peripheral wall of the support base to be fitted and fixed. Each of which is provided with a plurality of gaps that run backward from the front end portion between the contact portions between the outer peripheral surface of the valve body and the inner peripheral surface of the supporting base body. The valve body in the gap is configured to be elastically deformable outward by hydraulic pressure.

  When the nozzle is not in use, the inside of the dispensing cylinder is hermetically shut off from the outside by the valve body of the valve member, preventing oxidation and drying of the remaining liquid in the dispensing cylinder, resulting in no solidification of the liquid and clogging. Although it is an excellent one that can smoothly dispense liquid without any problems, it has a drawback that its structure is complicated.

  The present invention has been made in view of the above-described points, and it is possible to easily eliminate clogging even when the contents are solidified in the nozzle, and to discharge the contents to the hand. In this case, a container with a nozzle that can be scraped without placing a burden on the hand and that can maintain high airtightness in the nozzle by combining with a closing member is proposed.

As a first means, in a container with a nozzle comprising a discharge head 12 having a nozzle 11 projecting on a container body A and configured to discharge the stored liquid in the container body A from the nozzle 11 by a discharge means, the nozzle 11 outer circumference, so as to protrude the tip from the nozzle 11 tip, the tubular body 20 and fitted and fixed for the flexible solidified residual liquid squeezing formed of a material rich in elasticity, the distal end surface of the cylindrical body 20 A closing member 31 provided with a closing plate portion 30 that is closed by pressure-contacting b was detachably provided on the nozzle-equipped container 1.

  The container body A can be a so-called bottle-type synthetic resin container body that stands up from the neck portion with a diameter reduced from the body portion, and various other types of container bodies can be used depending on the discharging means, for example, an aerosol can Or a container body with a bottomed cylindrical shape in which the upper end of the body portion is opened as it is. Moreover, when the discharging means is a squeeze type that will be described later, a structure in which the body portion is configured to be squeezed is used.

  As the discharge means, a push-down head type pump or a pressure accumulation pump attached to the container body A, an aerosol type discharge mechanism provided in the container body A, or a squeeze type discharge means by squeezing the body of the container body Various discharge means such as a discharge means for discharging the stored liquid by tilting the container are applicable. Further, the discharge head 12 is located on the container body A and can be operated up and down as in the case of the pump-type discharge means, or the discharge head 12 as in the case of the discharge means by body squeezing. It may be fixed on the body.

As long as the tip of the cylindrical body 20 protrudes from the tip of the nozzle 11, the cylindrical body 20 may be fitted to the nozzle tip as shown in the example shown below, or may be fitted to cover the entire nozzle. May be. Further, in the case of a form that is fitted to the nozzle tip, a locking surface for locking the rear end surface of the cylinder 20 may be formed on the outer periphery of the nozzle. As the material of the cylindrical body 20, a synthetic resin, an elastomer, or the like can be preferably used. The protruding width of the cylindrical body 20 from the tip of the nozzle 11 is not particularly limited, but is preferably a protruding width that can be bent relatively large when pressed from the position facing the outer surface. Specifically, it is preferably about 5 mm to 15 mm, but is not limited to this.

  As the second means, in the first means, an engaging means for preventing the slippage by engaging with the outer peripheral surface of the nozzle 11 and the inner peripheral surface of the cylindrical body 20 is provided.

  As the engaging means, means for engraving and screwing threads on the outer periphery of the nozzle 11 and the inner periphery of the cylindrical body 20 in addition to the engaging means of saw blade-like annular protrusions of the embodiments described later. In addition, it is also possible to project a recess and a protrusion that fit into the outer periphery of the nozzle 11 and the inner periphery of the cylinder 20.

  The main purpose of providing the closing member 31 is to seal the tip discharge port of the nozzle 11. Therefore, various forms can be selected as long as the above conditions are provided. For example, outside the cover type as in the embodiment described later, a belt body is extended from a cap-like portion fitted on the upper surface of the discharge head 12, and a closing plate portion 30 is vertically suspended at the front end portion of the front surface of the cylindrical body 20. You may comprise so that it may press-contact.

As a third means, a discharge head 12 having a nozzle 11 projecting forward is provided above the container body A and the mounting cap 10 fitted to the mouth neck portion 3 of the container body so as to be able to be pushed down in an upward biased state. In a container with a nozzle composed of a pump configured to discharge the liquid in the container from the nozzle 11 by the vertical movement of the discharge head 12, the tip of the nozzle 11 protrudes from the tip of the nozzle 11 on the outer periphery of the nozzle 11. In this state, a solidified residual liquid handling cylinder 20 formed of a flexible and elastic material is fitted and fixed, and a lower cylindrical wall 41a is fitted to the outer periphery of the mounting cap 10 and a flange 41b is fitted. An upper cylinder wall portion 41c extending around the lower portion of the discharge head 12, a fixed cylinder 41 having an outer surface of the upper cylinder wall portion 41c as a fitting surface c is provided, and a rear end portion forcibly fitted to the fitting surface c A fitting base 31a having a ring-opening cylindrical shape; and an extension on the fitting base 31a. In addition, a closing member 31 including a main body portion 31b having a rear end opening that covers the discharge head 12 and the nozzle 11 and presses the closing plate portion 30 at the tip thereof against the front surface of the cylindrical body 20 is provided.

  The container with a nozzle of the present invention has a very simple structure in which the cylindrical body 20 is fitted and fixed to the outer periphery of the nozzle 11, and even if the residual liquid in the nozzle 11 is solidified, it can be easily removed by handling the cylindrical body 20 In addition, since the tip is flexible, it can be used safely and comfortably without inconvenience such as pain even if the tip is rubbed with the palm of the hand when the contents are taken out by hand.

  Further, if an engagement means for preventing the nozzle 11 from coming out by engaging with the outer peripheral surface of the nozzle 11 and the inner peripheral surface of the cylindrical body 20 is provided, the inconvenience such as disconnection of the cylindrical body 20 during use is more reliably ensured. Can be prevented.

  Further, when the closing member 31 including the closing plate portion 30 that closes the distal end surface b of the cylindrical body 20 by pressure contact is detachable, the inside of the nozzle 11 is sealed when not in use. As a result, the liquid in the nozzle 11 can be prevented from solidifying. In particular, if the closing member 31 is in the form of a cover, the upper part of the container can be covered when not in use to prevent adhesion of dust and the like.

In the case of the closing member 31 in which the fitting base portion 31a is forcibly fitted to the fixed cylinder 41 as in the third means, the fitting base portion 31a is in a stable state without play due to the flange portion 41b and the fitting surface c of the fixed cylinder. As a result, the end opening of the cylindrical body 20 can be more reliably closed by the closing plate portion 30, and the residual liquid in the nozzle can be prevented from being dried and solidified. Further, even if the discharge head 12 is a push-down head type movable one, the sealing performance in the nozzle 11 can be further improved by the reliable pressure contact of the closing plate portion 30. Further, since the blocking member 31 can cover most of the nozzle 11 and the ejection head 12, it is possible to prevent dust from adhering to these portions as much as possible.
